JSF Chart Creator

[anujcb]

Any comments on JSF / Chart Creator having any Ajax support capability ? like Ajax4JSF wrapper etc ...

This would be fantastic... Imagine a JFree chart dynamically updating in the page without page re-load...

Any pointers on anyone working on this ... if not I will try and make something using Ajax4Jsf

-A-

I just completed a prototype application using ICE Faces components and Jfree charts. The best part is the interactiveness it gives, i can look at charts almost realtime, change the axis range, dynamically overlay multiple data sets all without refreshing the whole page.

Hello,
I want to do a TimeSeries graph (like the pricevolume demo) but with bars (reprensented by the volume).
In the example, they make a chart, and change the renderer of the chart's plot.
I would like to do the same but i can't find how...
For now, I just return a TimeSeriesCollection in the datasource property with the type timeseries.
Is there a way to define that it should be rendered in bars and not axis ?
Thanks.

I solved the problem, I commented the //emptySession(sessionMap, id);
in ChartListener and also Chartlet, now its working fine.

Thanks

Hello all, I'm bit confused in using the Chart Creater. The <c:chartAxis> is assumed to add Child component to customize an axis. I tried it with xyline chart as provided in demo. and works fine :

Code: Select all

<c:chart id="chart2" 	datasource="#{myBack.firstXYDataset}" xlabel="Month" ylabel="Paid $" type="xyline" is3d="false" legendBorder="false"	legendFontSize="12">

	<c:chartAxis  id="cntAxis" label="Count" 
		verticalTickLabels="true" tickMarks="true" 
		datasource="#{myBack.secondXYDataset}"
		tickLabelFontSize="12" />

</c:chart>

But when similar approach is taken for line chart it only shows primary range data set.

Code: Select all

<c:chart id="chart3" datasource="#{myBack.categoryDataset}" xlabel="Month" ylabel="Paid $" type="line" is3d="false" legendBorder="false" legendFontSize="12">

<c:chartAxis  id="cntAxis1" label="Count" verticalTickLabels="true" tickMarks="true" datasource="#{myBack.secondaryCategoryDataset}" tickLabelFontSize="12" />

</c:chart>

Shouldn't this code be working??
Please any Help??

[shamesh_joshi]

if ChartAxis's rendered="false" is set, the renderer still renderes the chartaxis.

Code: Select all

<c:chart generateMap="true" id="chart9" datasource="#{myCharts.categoryDataset}"
			xlabel="Month" ylabel="Paid Amount" type="line" is3d="false"
			legendBorder="false" legendFontSize="12" startAngle="30">
			<c:chartAxis id="cntAxis123" label="Count" verticalTickLabels="true" rendered="false"
				tickMarks="true" datasource="#{myCharts.secondaryCategoryDataset}"
				tickLabels="true" tickLabelFontSize="12" />
			
		</c:chart>

Hello everybody,


Mr cagatay_civici, please I am facing problem with chartcreator. when I add jsf-comp.jar to my project it dosen't work and tomcat indicate error like this:

org.apache.jasper.JasperException: L'uri absolue: http://sourceforge.net/projects/jsf-comp ne peut être résolu dans le fichier web.xml ou dans les fichiers jar déployés avec cette application
org.apache.jasper.compiler.DefaultErrorHandler.jspError(DefaultErrorHandler.java:51)
org.apache.jasper.compiler.ErrorDispatcher.dispatch(ErrorDispatcher.java:409)
org.apache.jasper.compiler.ErrorDispatcher.jspError(ErrorDispatcher.java:116)
.....

I configured jsf and it works good with my project. when I add chartcreator to my project as a user librairy it indicate the error above.
Why chartcreator jar contains "faces-config.xml"? already I have it with my jsf??!! should I delete it or copy its content to my old "faces-config.xml".

Please help me I need your help because I m blocked at this stage.


Best regards.

No, you leave the faces-config.xml file where it is (in the meta-inf dir) inside the jar.

This is the correct packaging for JSF components.

thanks Chris Graham,

Now it works good, I just added all jars found in the webapp example lib directory to the lib of my project and it works. maybe the problem was that one jar was messing in my first example.

Best Regards.

Hi,
Is it possible to customize the pie chart labels in jsf chart creator? i.e., right now all the labels are just the category you use in the dataset (A,B,C,etc.), but I would like to have the % numbers in there as well (A 10%, B 15%, C 75%).

This is possible in JFreeChart according to the docs, but I'm just not sure how to access it in my JSF page with chart Creator.

Thanks

Hi all, it seems the below post might address my problem of showing percentages on the legend/labels on pie charts. The legendContainer still isn't integrated, but is it available anywhere? Is JSF chart creator still being maintained or has it been superseded?
Thanks again

Dear JFreeChart Community,

I'm pleased to announce that JSF ChartCreator's new version 1.2.0-M1 is ready, This release contains many new features and several bug fixes.

Hi Cagatay.
I sent you the additions that I made to your component to allow for alternative legends (the legendContainer attributes) for pie charts.

Did you get it and have you had a chance to implement them into your source?

By looking at the TLD, it seems to not support this type of chart. Does it? Are there any plans if it does not.

Thanks!

[sagefool1975]

have big white bars in them. Looking at general jfreechart posts it looks like this is because the renderer now has margins. There doesn't appear to be anyway to set the margins to zero in chartcreator, any chance this could be patched? Seems easy enough to do.
